LOCK.

SPECIFICATION forming part of Letters Patent No. 774,970, dated November 15, 1904. Application filed vDecember 4, 1903. vSerial No. 183,820. (No model.)

To tir/ZZ whom, it 711,04/ concern.-

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle,

King county, Vashington, have invented certain new and useful Improvements in Locks, of which the following is a' full, clear, and eX- act description.

My invention relates to locks and latches, and particularly to that type of a lock known as a unit lock, in which all of the parts are alssembled before the lock is applied to the c oor.

Among the objects of this invention are to provide certain new, economical, and effective features of construction, hereinafter more fully set forth. Incidentally the construction is such that I am enabled to employ sheet or wrought metal in forming nearly the entire mechanism. In the past it has been common to construct many of the parts of castings. By my invention this is avoided, and I attain certain economies of construction heretofore impossible.

Other objects and advantages will be apparent from a reading of the following description.

In the drawings, Figure 1 is a plan view of my improved lock, showing a portion of a door at the rear thereof. Fig. 2 is a side elevation of the parts shown in Fig. 1, said view being taken partly in section and one of the side plates being removed. Fig. 3 is a vertical section of the lock, some of the parts being shown in elevation, said section being coincident with the axis of the knob-spindle. Fig. 4 is a crosssection of the knob-spindle, showing the. rollbacks and a portion of the latch-slide in side elevation, the latch-slide bring retracted by rotation of the knob-spindle. Fig. 5 is a side elevation of a roll-back for the knob-spindle. Fig. 6 is a side elevation of a roll-back for the key-spindle. YFig. 7 is a View similar to Fig. 4, the roll-backs being shown in different position, the latch-slide being retracted by the key-spindle. Y Fig. 8 is a side View of the supporting barrel or hub detached and a portion of the side plate. Fig. 9 is a longitudinal sectional view of the knob-spindle with one of the knobs attached thereto and showing a night-latch and key-controlled operating mechanism in side elevation. Fig. 10 is a AView ofthe inside of the outer section of the outer knob, showing a cylinder-lock in end elevation. Fig. l1 is an end elevation of the parts shown in Fig. 9 looking from left to right. Fig. 12 is a sectional view of the nightlatch-controlling member. Fig. 1-3 is an end view of the same. Fig. 14 is a section on the plane of the line a d, Fig. 9, showing the night-latch and controlling member in elevation, the night-latch being in the on position. Fig. 15 is a similar view, the position of the night-latch and controlling member being shifted to show the night-latch in the olf position.

1 is a portion of a door which, in accordance with practice, has a notch cut in the ystile thereof to receive the lock.

2 and 3 are side plates, which may, if desired, constitute escutcheon-plates, but whose main function is to support and hold the latch mechanism in place. If desired, escutcheonplates 4 5 may be separately formed and secured to the side plates 2 3. In practice the plates 2 3 may be formed of sheet metal. By this arrangement it is possibleto make the .side plates 2 3 of conventional form best adapted to the mechanical purpose for which they are intended, whereas the escutcheonplates 4 5 may be first given any desired design or ornamentation and then secured in any well-known manner to the plates 2 3. The plate 3 in the particular form shown constitutes a part of the latch-carrying frame, and one end may be bent up to form the faceplate 6.

7 is a latch bolt or head,which may operate through a perforation or recess in the faceplate 6. Between the plates 2 and 3 may be .located a third plate 8, one end of which may be bent up and secured to the plate 3. as at 81, so that it, together with plate 3, will constitute said latch-carrying frame. The other end of plate 8 may be also bent up and connected with the face-plate 6, as at 82, to rein-` force the same. Theplate 8 may be formed of sheet metal. This plate is so shaped that a space is formed betweenthe plates 3 and 8, in which the latch mechanism proper is 1ocated.

IOO

-or body portion of the roll-back 11.

9 is a latch-slide, one end of which is bifurcated and hooked at 91 or otherwise suitably formed to be engaged by the roll-backs 10 11. The other end of the latch-slide 9 is secured to the latch boltor head 7 -for eXample,by means of a hooked portion 92 engaging' with the pin 71 on the said latch-bolt 7.

93 is a perforated bearing carried by the latch-slide 9, through which bearing may pass the stem 72 of the latch bolt or head 7. Thus the latch-bolt 7 may be guided partly by the side plates and partly by the bearing 93. 12 is an ueasy spring, which may surround the stem 72 and one end of which may bear against the latch-bolt 7, while the other end may take up against the bearing 93.

13 is a second spring, which may bear one end against the bearing 93 and the other end against astationary tubular barrel-bea ring 14, which constitutes the bearing-supi'iort for the knob-spindle 15. To Steady that end of the spring against the barrel 14, I. may provide a stud 141, with which the spring 13 may engage. The barrel 14 is secured to the frameplates 3 and 8 and has a recess or perforations therein in which are located the roll-backs 10 11, the recesses or perforations being of such size as to permit the rocking of said rollbacks. The roll-back 11 is carried by the knob-spindle 15, which spindle is tubular in form. This knob-spindle 15 is also recessed or perforated to allow the introduction of said roll-backs, and said recesses or perforations are in the particular form shown formed so that said roll-back 11 is when the parts are assembled held in such relation to the knobspindle 15 that it always turns therewith and cannot rotate independently thereof. This end is accomplished by forming notches 151 (see Fig. 9) at the end of the recess or perforations in said knob-spindle, said notches being of a suitable width to receive the shank The perforations or recesses in said knob-spindle 15 are of such shape as to permit theother roll-back, 10, to be rocked independently of said knob-spindle by the action of a separate key controlled spindle 16, so that by this means the bolt7 maybe retracted if the knobspindle should be locked. In the outer knob is carried a cylinder-lock 17, arranged to receive a key 13. 172 is an offset on the case 17 to prevent said lock from rotating in said knob. The roll-back 10 has an angularopening to receive said hey-controlled spindle 16, while the other roll-back, 11, may have a round opening of such a size as to permit the key-controlledspindle 16 to pass freely therethrough and be rotated independently thereof. The outer knob is preferably formed of two shells or sections which are held together by screws 19 19, which screws may pass through holesin the inner section and engage with screw-threaded bosses 20 2O on the inside of the outer shell. ln the preferred conl struction these two knob-sections comprise the two shells 21 22, which latter are reini forced on the inside for the purpose partly of j strengthening the knob, partly to afford secure support for the screws 19 and. bosses 20, l and partly to form bearings for the cylinderlock 17. This reinforcement is effected by plates 211 222, which are best seen in Fig. 9. Tithin these reinforcing-plates 211 222 two opposite annular shoulders are formed of a suitable size to receive and center the cylinder 17. The inner knob-section 21, together with its reinforcing-plate 211, is held in fixed engagement with the tubular knob-spindle 15, while the inner edge of the reinforcing-plate 222 is preferably spun outwardly and around the edge of the opening in the outer section 22. This affords one means to securely clamp said section and reinforcing-plate together and incidentally form a smooth passage er bearing for the hub 171 of said lock.

23 is an annular covering-plate which overlies and lhides the screw-heads 19 19 when the parts are assembled. The inner edge of the said plate 23 surrounds the knob-spindle and bears against the end of the barrel 14 and so as to be held in place thereby. The night-latch comprises means for locking the tubular knobspindle 15 against rotation in the stationary bearing 14. The night-latch comprises a dog 24` pivoted in the tubular spindle 15. 241 is a locking-nose on said dog 24, which is arranged to project outwardly to engage with a notch 142 in the barrel 14. (See Figs. 3 and 3.) This locking-nose 241 is or may be pressed outwardly by means of a spring 242.

243 is a night-lateh-controlling member, which may be a ring having a cam or camsurfaces 244 therein, which overstand the end of the locking-dog 24. When the controlling member 243 is turned so that thelow part of one of the cam-surfaces 244 rests above the end of the dog 24, the locking-nose 241 will project outwardly and engage in the aforesaid notch 142 in the non-rotatable bearing 14. inasmuch as the nose or end of the dog 24 likewise passes through a suitable perforation or slot in the knob-spindle 15 it will be seen that when the dog engages with the stationary barrel the knob-spindle will be locked against rotation. Them however, the controlling member 243 has been turned to the proper degree, so that a high part of one of the camsurfaces 244 will stand over the end of the locking-dog, the latter will be depressed, so that its locking-nose 241 will be freed from the stationary barrel 14. Vhcn the dog is in this position, the knob-spindle is free to turn. The controlling member 243 is loosely mounted on the knob-spindle. For convenience sake a notch may be formed in each of the vcam-surfaces 244'at the position wherein the dog 24 is freed from the barrel 14. This notch serves to receive the edge of the dog 24, The latter being spring-pressed holds the conl l i i l 'lOO ,vide clearance for the end of the stem 72 of the trolling device 243 from tally shifted.

25 is the inside knob, which may be suitably secured to the inner end of the knobspindle l-for example, by means of a pin 251.

26 is a bridging member which may span the space between the plates 3 and 8 and is secured thereto. The function of the bridging member 26 is to reinforce the said plates 3 and 8. One end of the bridging member 26 may be oset, as at 261. In Fig. 1 a portion of said bridge is broken away to show said odset. This offset portion, together with becoming accidenthe plate 8, forms a double thickness of metal, which may be perforated and tapped to receive the threaded end of an adjusting-screw 27, by means of which the side'plate 2 and 8 maybe drawn toward each other and clamped firmly against the sides of the door 1 when the lock is in place.

` From the foregoing it will be seen that by far the majority of the parts may be formed of wrought or sheet metal. The various plates may be riveted or otherwise fastened together. Many of the parts may be connected integrally. The stud 141 may have a recess therein, as indicated in Fig. 2, to prolatch bolt or head. This stud may be riveted to the tubular bearing 14. The perforated bearing93, carried by thelatch-slide, receives the thrust of the heavy knob-spring 13 as well as the thrust of the easy spring 12. Inasmuch as the escutcheon-plates 4 5 may be formed from sheet metal and in any suitable design and inasmuch as the said escutcheonplates 4 are reinforced by said side plates 2 3, the former may be made of very light material, resulting in great economy.

In operation to prevent the latch-bolt from being operated by the knobs the user turns the controlling device 243 so that the dog 24 engages with the stationary barrel-bearing 14,A whereupon the tubulark knob-spindle 15 is locked therewith and neither knob can be turned. The latch-boltmay, however, be rel tracted by means of a key 18, which may be inside in the cylinder-lock 17, which key when turned rotates the spindle 16, and thereby the roll-back 10, which in turn engages the latchslide 10. retracting the same and incidentally the latch-bolt 7.
